7/18/23 - This is a 1970 production Lothar Walther 7.65mm to 4mm conversion kit. The box label indicates this could be used for either the PP or PPK, but the hand-writing suggests this was previously used with a PPK. The kit comes with everything shown; original box, loading tool, barrel, and cartridges. The barrel is 1970 dated by Lothar Walther. The bore has some mild rust in the grooves and signs of previous use, but the rifling is still strong throughout.
